On the second video he actually has 4 seconds to do something with the ball. There's a running lane to his right that he never sees.
And that in a nutshell is the problem. Everyone in the world knows he's got a crap line -- the Coaches and the players on both sides. That means he was clearly told something to the effect of "if you want to live, you don't have time to scan the field, play your progressions and get rid of the ball fast". Ok, they really said 'get rid of the ball fast to make up for the poor line and non-existant running game'. That IS the gameplan.
Now, when he gets hit before the 3rd step on a 3 step drop, it's 'why didn't he feel the pressure?'. Of course, everyone here thinks that the good QB's 'just feel' the pressure...not take their eyes off the downfield receivers. If he takes his eyes off the downfield recievers, he looses the timing window the play was designed to be thrown into and then everyone says 'he can't throw with timing'. Of course, if instead, he scrambles into the arms of the defensive line that just won a 3 on 5 or 6 battle... But hey, #QBRulz. If he plays tough and the window opens -- and of course we all see it happen on the screen -- 'buzz' -- oh crap, that was the 2 second mark and at exactly the same time, one or three of those very, very angry defensive line men who managed to get to him because of missed assignments, bull rushes, blocking to the wrong side, etc. are in his face. And again, it's his fault.
There are only a handful of QB's in the history of the game that had all of those skills early in their careers. And the ones that did have had the luxery of having several parts of the game working for them to build up confidence. When has RT learned to trust any part of the game here? RT knows he's the focal point of the game plan, knows he has to make plays, and is forcing things -- looking downfield for too long, locking on receivers, and not paying attention to the rush because he's desperate to make a play.
I'm not saying he's the answer. I'm just saying I can't imagine any of the QB's I've ever watched in my lifetime being successful here over the last 5 years. RT might not be the answer, but all of the time spent looking at a play with 11 people involved and thinking if we just had one person throwing the ball better is just plain magical thinking.
